Wat Phra Ram was built in 1369 A.D. by King Ramesuan at the cremation site for his father, King Uthong. Since he reigned initially only for one year, it is assumed the construction was completed by this successor King Borom Rachathirat I, or by King Ramesuan during his second reign.

The temple has been restored a few times in the subsequent centuries, during the reign of King Borom Trailokanath, and later by King Borom Kot. The temple compound houses a large prang and many chedis.
